It’s Like No Other Mattress That’s because TEMPUR® material is not typical memory foam. Our proprietary formulation changed the way the world sleeps. And it can do the same for you. TEMPUR material responds to your body’s temperature, weight and shape for truly personalized comfort and support. As it conforms to your body, TEMPUR material minimizes pressure points that keep you awake. TEMPUR® material dramatically reduces motion transfer so your sleep partner’s movement won’t disturb you.
